ELIAS A. C. SMITH, OF BALTIMORE, MARYLAND.

COIPER--IVIATTE CONVERTER.

Application fried october t,

To all whomit may concern:

Be itknown that I, ELIAS A. C. SMITH, a citizen of tl` e. United States, residing in the city of Baltimore and State of Maryland, have invented certain new and useful Improvements in Copper -Matte Converters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

In the bessemerizing of copper matte,

acid lining, or a non-eorrodible lining, such. as magnesite brick or chrome brick, the operation has heretofore, in so farvas I am aware, always been attended With the ejection from the converting vessel of, large quantities of the molten matte under treatment. The quantity of matte thus ejected frequently amountst from twenty-tive per cent. (25%) to thirty per cent. (30%) of theentire charge. It is termed in the art secondaries and must be remelted in the matte-making furnace in order to be recovered for subsequent use. 'The additional expense of the fuel required for this remelting, and the inconvenience and annoyance of the ejectionA of so considerable a quantityl of the contents of the converting` vessel are disadvantages which my present invention is designed to correct.

In the accompanying drawings, Figure l represents, iii-longitudinal section, the main elements of a converter, embodying my improvements; Fig. 2 represents a like view of a niodication thereof; and Fig. 3 represents a transverse section taken upon the line 3-3 of Fig. l.

Similar letters of reference indicate'similar parts throughout. the several views.

Referring to the drawings, A indicates the cylindrical shell of .the converter, which is riveted tothe rings B. and which is adapted to be osrfillated or rocked upon the rollers C.

M indicates the converter lining. penetratedby the twyers N.

In the form of the converter shown in l, the outlet O for the passage of the gaseous products of the besseinerizing operation is shown as located intermediate of tht;` ends of the converter and at a point Specification of Letters Patent.

about midway thereof, to one side of the central supporting ring. In the form of the converter shown in Fig. 2, the outlet O isarranged at the extreme right hand end of the converter. These locations indicate suitable places for locating the outlet, the particular `location thereof along the length of the converter being chosen in accordance with convenience.- In any event, however, whether the outlet port yis located at the eXtreme end of the converter as shown in Fig. 2, or at some point intermediate of the ends as shown in Fig. 1, the characteristie feature of my invention consists in s o arranging the twycrs with respect to the outlet port that the outlet port will be substantially out of range of the ejeeting or slopping7 action of the twyers. Thus, as shown in Fig. l, the series of twyers on each-side of the outlet port O stops appreciably short of said outlet port; and in like manner, the series ofI tWyers shown in Fig. 2 stops appreciably short of the outlet port OC In other words, thatI portion ofthe converter. below the outlet port, in both instances, is devoid of twyers the outlet port being located substantially beyond the twyers. By this expedient, the matte thrown up by thel violent injection of the blast into the charge strikes the roof of the furnace and falls back into the charge, instead of being ejectedin large part through the outlet port, and, as a result, in converters having the twyer arrangement 4described and shown, the loss. and annoyance due to the formation of seeondaries, incident to the usual operation, is entirely avoided.

What I claim is:

l. A conif'erter for bessemerizingl copper matte having a series of twyers for the adv` mission of the bessemerixing blast and hav-v ing an outlet port for the escape of the gaseous products of the bessemerizing operation` said outlet port being substantially out of range of the sloping action of the twyers; substantially as described.

2. A converter for bessemerizing copper matte, having a series of twyers for the admission of the bessenfxerizing blast, and having an outlet port for the escape of the'gaseous products of the bessemerizing opera- .issus tion, that portion of the converter below eration, said outlet port being located be- 10 the outlet port being devoid of twylers; yond the series oftwyers; substantially as.
